To all whom it may concern; I

Be it known that I, ALEXANDER is LEE EWERS, a citizen'of the United States, residing at Durmid, in the county of Campbell and StateofVirginia, have invented new and useful Improvements inPrinting and Bronzing Mechanism for Cigarette-Machines, of which the following is a specification.

This invention relates to cigarette making machines, particularly to an attachment placed on certain of these mach nes for printing labels, ornamental devices, trade marks and other representations on the continuous wrapper strip as it passes through the machine to be folded about a filler.

The object of the invention is to provide a simple apparatus for printing on a continthe webis wrapped about a tobacco filler to form a rod and the rod cut into cigarette lengths, each cigarette will have impressed upon it in the same relative position,- the desired label or other device.

device properly disposed about said cylinder impress the device on the strip.. Heretofore in these printing machines the impression cylinder was geared to the printing rolls and bronzing device and driven positively therewith. It is necessary, therefore, if after operating for a time making cigarettes of a given length, cigarettes of some other length be desired, not only to change the printing rolls for others with the dies a different distance apart circumferentially, but another impression cylinder of suitable diameter must be substituted for the one previously used. This is due to the fact that the aforesaid parts are positively geared together and any change whereby printing rolls of one diameter are replaced by rolls of a different diameter necessitates a change of impression cylinder that the surface speeds of the c linder and rolls may be the same as the speed of the wrapper strip.

With the device of the present invention, the impression cylinder rotates freely on a fixed stud and is driven wholly by the frictional contact of the wrapper strip passing around it. Hence, whatever the speed of said strip the peripheral speed of the impression cylinder will be the same. The printing rolls are driven as usual through gearing receiving motion from the same source as that which drives the wrapper strip so that any change of speed of one will necessarily change the speed of the other.

In the accompanying drawings which show one embodiment of the invention, Fig: ure 1 is a vertical longitudinal sectional view of the apparatus showing the impression roll, the printing and size applying mechanisms and the bronzing device. Fig. 2 is a horizontal sectional view on the line 2-2. s l

In the drawings 10 indicates a vertical supporting plate for the printing mechanisms which may be inclosed if desired by a suitable casing. These mechanisms preferably comprise animpression cylinder 01' 7 13 of rubber fitted in a groove therein around which roll the continuous strip or web A, which is to form the cigarette wrapper passes as it is drawn from the reel to the filling and folding devices, the rubber surface formed by the band 13 affording sufficient friction for the wrapper to rotate the roll without danger of the wrapper slipping.

On opposite sides of the impression roll 10, preferably in diametrical relation are printing rollers or dies 14, 14 fixed on short shafts 15, 15 driven by gearing in well known manner. The printing rollers or dies are removably secured on their shafts to permit ready disengagement when the printed designs are to be changed.

A- reservoir or fountain 16 secured to the plate 10 a short distance from the printing roller 15 contains a sizing when designs are to be printed in bronze and ink when two colors are to be printed. A corresponding reservoir or fountain 16 is disposed in similar relation to the other printing roller15 and contains ink, which is of a different color from that in fountain 16 when printing in multi-color. A roller 17 rotates in the fountain16 to raiseithe size or ink therefrom and transfer it to a roller 18 that vibrates between the roller'l'? and a roller'19 mounted on a shaftjournaled in theplate 10. The vibrating roller 18 is carried on one end of a swinging arm 20 pivoted at its other end on a pin 21 projecting from the plate 10. Aneccentric 22 on a shaft 23 turning in a bearingon the plate 10, is connected, as shown, to the swinging arm 10 and slowly vibrates the' roller 18 between the rollers 17 and 19. A metal roller 24 on the shaft '23. receives the sizing or ink from a composition roller 25 that runs in contact therewith and also with the roller 19. The

roller 24 is carried by an adjustable bracket" bracket 28 and has a limited amount of play therein to assure its contact with'the printing roller or die. i

On the opposite side of the impression roll 7 11 is a similar grouping of ink distributing rollers as indicated by the numerals 19*, 2%,25Fand 27. v

The "continuous cigarette wrapper A is preferably guided over rollers 29 and made tocontact with more than one halfthe circumference of the impression roll.

Below the impression roll his a receptacle 30 containing bronze powder, within which receptacle revolves a roll 31,'preferably made of aluminum and covered on its periphery with plush; This roll collects the bronze powder on its plush covered periphery and transfers it to. a revolving applying e roller 32 which has raised surfaces 33 also copies of thirpatent may he obtained :01-

covered with plush that'receive the powder and transfer it to the wrapper strip A,the surfaces 33' contactingwith said wrapper at the precise places where the'rol-ler or die 14 left imprints in sizing thereon. The printing roller or die next impresses in color the design over the bronze. A plush coveredroller 31 running in contact with the wrapper A removes all surplusbronze powder from said wrapper and by means of a revolving brush '35 this powder is brushed from the roller 34 back into the receptacle. \Vhat I claim is a f Ina machine for printing ona continuous traveling strip, inv combinatioma fixed stud, an impression rollers freelyrotatable about andsupportd on said stud, a, pair of guide. rollers for guiding the strip tov be printed around the face of said impression roller said guide rollers being so located that, sald portion of: the. circumference of the roller strip-is maintained in Contact with the; major and s0 that/said roller isrotated solely by said strip, a rotatable shaft mounted at a fixed point, a printing roller carried by said shaft andhaving a pair of oppositely disposed segmental printing dies adapted to touch the. strip on "said impression roller as 7 nesses,
